Mumbai, September 11: Today marks 16 years of September 11, 2001, terrorist attacks or 9/11 terror attacks of the United States. It was on this horrifying morning in New York, 16 years ago, that two aeroplanes crashed into World Trade Center complex into the North and South Towers or Twin Towers. This apart, another plane crashed into Pentagon (the headquarters of the United States Department of Defense) in Arlington County, Virginia.

The aeroplanes were hijacked by 19 al-Qaeda terrorists. These planes belonged to two major US passenger air carriers (United Airlines and American Airlines) that departed from airports to California. After an hour and 42 minutes of the crash, both 110-story towers collapsed.

The intensity of the attack was so high, it resulted in the complete collapse of all other buildings in the World Trade Center complex. The Pentagon was also damaged partially due to the plane crash. More than 3000 people lost their lives in the deadly attack, including 19 hijackers.

The fourth hijacked crashed in a field in into a field in Stonycreek Township near Shanksville, Pennsylvania. Reportedly, 6,000 people were saved in the terror attack.

Here are some images of the deadly attacks that shook the US 16 years ago.

Osama bin Laden, the leader of al-Qaeda terror group, had first denied being responsible for the attack. However, in 2004, he took the responsibility for the attacks. Osama was killed in Pakistan’s Abbottabad on May 2, 2011, at midnight by United States Navy SEALs of the U.S. Naval Special Warfare Development Group under the operated code-named as Operation Neptune Spear.
